OF CIIIGAGO, ILLINOIS FREIGHT GAB Application led March 8,

V.This invention relates vto freight cars and One ob `ect ofthe invention is to provide cars which may the car from the top forthe purpose of conveniently loading and unloading the car.

-Another object is to provide a roof struc- 10' ture for cars having a plurality of sections separately mounted to permit opening one v or more sections independentl of the-others. Another object is to rovi e a roof structure for cars having ap urality of separately 15 mounted sections so interlocked that the locking of one section will hold all of the sections locked in closed position.

Another object is to provide a sectional roof structure of the character referred to to make and install, strong and durable, easy to ma nipulate, eliicient and reliable in use, an protected against leakage of water or the like. Other objects will be in part obvious and in 25 part pointed out hereinafter.

The invention accordingly consists in the features of construction, combination o elements, and arrangements of parts, which will be exemplified in the structure hereinafter of the application of which will be` indicated in the sub-joined claims.

In the accompanying drawings in which is shown one of the various possible embodiments of the invention Fig. 1 is a top plan View of a box car embodylng the invention.

means taken substantially on lthe line 7 -7 'of Fig. 3.

' Fig. 8 is a sectional view taken on the line 8--8 of Fig. 3.

Fig. 9 is an enlarged top plan-view of a.-

ortiion of the roof and showing one of thev sections in open position.

Referring to Fig. 2, a box car designated l is shown, provided with the usual slidmg door 2 and the sectional roof` to which this application isprimarily directed.

As shown in Fig. 1, the roof comprises a plurality of sections, six in the illustrative embodiment, A, B, C, D, E and F, which, when in closed position, interlock to form in effect an integrally tight roof for the car.

Referring to Figs. 3 preferably consists of one or more panels of roofing material, 3 which may be of wood or other suitable material, covered by` a waterproof sheet 4, which sheet metal, may be secured to the under side of the sections to reenforce them.

The sections E, A and D are separately' hinged to a plate 6 secured to one side of the car along its upper edge, and C are similarly hinged to a. similar plate 7 similarly secured to the other side of the car.

Plates 6 and 7 are preferably curved as at 8 and the ends of ribs 5, which contact with the curve 8, are similarly curved to facilitate the swinging movement of the sections.

As shown in Figs. 4 and 5, the opening movement of the sect-ions may be limited by a chain or cable 9 secured to .the section and the interior of the car side.

To prevent leakage at the meeting edges of the several sections, each section is provided with waterproof edge strips 10, preferably consisting of corrugated plates constructed when the several sections are in closed position.

As best shown in Fig. 6, the sections 'adjacent the car ends may be provided with waterproof strips 11 preferably in the form of sheet metal angle irons bolted to the section and arranged to hang downward outside may be of sheet. 5, preferably of and 8, each section D and sections F, Bl

Sections E, A and D may be provided with posil a runway 12 to rest on sections F, B and C Section A is when the sections are in closed position.

The interlocking arrangement of the several sections is best shown in Figs. 1 and 8. provided with extension plates 13, preferably of the form shown in Fig. 8,

which plates are bolted to sectionA and eX- tend over and contact with the upper surfacesv of sections B, E and D respectively,

thus` holding said latter sections in closed positlon. Section B is provided with similar extension plates 13 which extend over-and -contact with the upper surfaces of sections F and C respectively and hold said sections in closed position. Similar plates'l may be provided on one or more of sections F, E, C and D. Thus, when all of the sections are closed, and section A is`locked,- all of the sections will be locked against opening.

Section A may be locked by a springpressed'latch 14 carried by section A and adapted to snap into a catch 15 carried by section B. As shown in Fig. 7, the latch may be padlocked againstv opening by a padlock 16 which passes through an eye 17 secured to the latch andan eye 18 firmly secured to the section A. In operation-gV section A is rst released by removing the padlock 16 and moving the latch 14 out ofcatch 15 and swinging section A back about its pivotal connection with plate 6. Thereafter one or more ofthe other sections may be opened as required.

The several sections may be provided with handles 19 preferably sunk in pockets, which handles may be grasped manually or by a hook of a suitable hoist mechanism to swing the sections to open position.

It will be seen that there is provided a construction of an essentially practical nature in which the several objects of the invention are attained. Y

Among other advantages the invention provides a practical roof structure for freight cars which may be opened for the purpose of conveniently loading and unloading the car. Such an arrangement is particularly advantageous for the 4loading and unloading of bulky or heavy commodities, as it permits the use of a crane, hoist or lift. It also facil; itates the loadingy of grain, coal or the like ing drawings is to be interpreted as illustrative and not in a limiting sense.

I claim 1. In combination with a box car, a roof comprising a plurality of sections, means for mounting the sectionssothatthey may be swung toopen andvclosed positions, means interlocking the sections in closed position so that the locking of one section will hold all of 'the'y sections locked against opening, means for limiting the swinging movement of the sections, and overlapping corrugated strips secured to the sections and bridging the joints therebetween'.

2. In combination with a box ca r, a roof comprising a plurality vrof sections, means for mounting each section so that it may be swung to open and closed positions, means interlocking all of the sections in closed posi- .tion so that thelocking of one section will Vhold all of the sections against opening, means for limiting the Swinging movement of .the sections, and weather-proof strips bridging the j ointsbetween sections.

In combination with a box car, a roof comprising a plurality of sections, means for mounting each section so that it may b e swung 'to open and closed positions, means for limiting the swinging movement of the sections,

means for locking thesections in closed position, and weather-proofstrips secured to the sections and bridging the oints therebetween. 4. In combination with a box car, a roof comprising a plurality of separate sections pivoted to each side ofthe -car and ada ted to be swung to o en and closed' positions, and means interloc {ingthe sections in closed position so that the locking of one section will hold all of the sections locked against opening. l

In testimony whereof, I have signed my name to this specification this 12th day of February, 1930.

through a chute. The several sections being independently mounted maybe opened separately, thus facilitating the opening of the car and permitting the car to be opened at one or more points without exposing other portions of the car.

lAs' many other embodiments may be made without departing from the scope of the invention it is to be understood that all'matter herein set forth or shown in the accompanylift
